Outline of Final Research Achievements

Collagen synthesis is essential in wound healing processes for conferring strength. We designed a large-animal experimental model to investigate the strength of wound healing and collagen deposition at the site of intestinal anastomosis following administration of a elemental diet, which contains high dose ornithine. The elemental diet may promote wound healing by stimulating collagen deposition at sites of intestinal anastomosis site and thereby strengthen the anastomoses. The elemental diet may promote wound healing by stimulating collagen deposition at sites of intestinal anastomosis site and thereby strengthen the anastomoses.

Academic Significance and Societal Importance of the Research Achievements

術後の栄養補給はさまざまなサプリメントが導入されているが、いずれも科学的な根拠が乏しい。本研究で、創傷治癒を促進する物資の科学的エビデンスが、実際行われている消化管吻合で証明されれば、学術的意義は高いと思われる。また、消化管吻合は消化器癌が多い本邦では多く行われている手術手技であり、吻合部の強度を上昇させるサプリメントが証明されれば社会的意義も高いと思われる。
